I'm not sure FUN is the correct adjective but now that I have all the proper layers and clothing it is more enjoyable. I kind of look forward to the accomplishment. Here in Central Texas, 25-32 is cold, normal winter at 33 to 40 is not a problem, with the right gear. Worst part of riding in < 50 degrees is my times are slower, cadence average is 5-8 less, but ride is pretty enjoyable. Since my time is limited, most of my 5-6 rides a week are 12-18 miles, but I'm always happier that I Went rather than I Didn't. My goal is to still get in 250/month during winter.
